Abstract

The present invention provides a piezoelectric device and an electronic device including the piezoelectric device. The piezoelectric device includes: a first piezoelectric plate; a vibration plate configured to contact a surface of the first piezoelectric plate; and at least one second piezoelectric plate arranged to contact the vibrating plate, wherein the first piezoelectric plate and the second piezoelectric plate have different resonant frequencies. Compared with typical technologies that apply both sound devices and vibration devices, the present invention can reduce the area occupied in the auxiliary mobile device. Accordingly, the piezoelectric device according to the embodiment can also be applied to the auxiliary mobile device. mobile device to reduce the size and weight of the auxiliary mobile device.

Description

technical field [0001] The present invention relates to a piezoelectric device, and more particularly, to a piezoelectric device usable as a piezoelectric acoustic device and a piezoelectric vibration device, and an electronic device including the piezoelectric device. Background technique [0002] Wireless calling functions such as the sending and receiving of voice or messages are themselves the main usage of a typical mobile terminal. However, with the recent development of smartphones, the wireless calling function is now a simple function, and performing various functions such as Internet, application, TV, navigation, and SNS has become the main use. [0003] Therefore, in order to conveniently use various functions of the smartphone, the display unit of the smartphone is enlarged, the size of the smartphone becomes larger, and rapidly developing technologies including network speed, operation, or pupil recognition enable users to more Use the smartphone terminal conve...
